SAND REEL.

Application filed May 7, 1925. Serial No. 28,674.

This invention relates to sand reels, and more particularly to means for supporting the sand reel frame on a derrick base.

An object of the invention is to provide a substantial installation for a sand reel in ment of the anchor bolts, and,

Figure 4 is a perspective view of a plate adapted to be arranged beneath the mud sill and adapted to receive the ends of the anchor bolts.

Referring to the drawings, the reference numeral 1 designates the main sill of the derrick. Arranged at spaced intervals transversely to the main sill are a plurality of mud sills 2, 3, and 4. The derrick legs 5 extend upwardly from the base in the usual manner and the crank shaft 6 is arranged over the mud sill 3. The sand reel indicated at 7 is adapted to be arranged over the mud sill 2 and the sand reel shaft 8 is provided with a sprocket 9 adapted to be driven from a sprocket 10 on the main shaft by means of a chain 11. The parts heretofore described are of the usual construction and form no part of the present invention except in the combination claimed.

In mounting the sand reel frame on the derrick base, I provide a pair of tail sills 12 arranged over the mud sills at right angles thereto and extending from the mud sill 2 to the mud sill 3. At each end of the sand reel frame, I provide a pair of anchor ceiVe the lower ends of the anchor bolts. Nuts 16 are arranged on the threaded lower ends of the anchor bolts, as shown. Theends of the plate are extended downwardly, as at 17, to prevent the bolts from slipping out.

The construction provided forms a substantial support or installation for the sand reel and properly anchors it in place, thus preventing the sand reel from shifting its position due to jarring or vibration during the operation of the parts of the well drilling equipment or due to operation of the sand reel.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. In a sand reel installation, a frame, bearings arranged at each end of said frame, each of said bearings being provided with a pair of vertical openings, and anchor bolts passing through said openings and extending downwardly, said bolts being adapted to be secured to the under side of a derrick sill 2. In a sand reel installation, a frame, bearings arranged at each end of said frame, each of said bearings being provided with a pair of vertically extending openings, anchor bolts passing through said openings, and a plate arranged beneath one of the derrick sills and connected to said bolts.

3. In a sand reel installation, a frame. bearings arranged at each end of said frame, each of said bearings being provided with a pair of vertically extending openings, anchor bolts passing through said openings, a pair of plates arranged beneath one of the derrick sills, the ends of said plates being provided with slots for the bolts 13, which extend through the bearings '14. and through the frame. These anchor bolts pass through the tail sills and extend downwardly on each side of the mud sill.

reception of said anchor bolts, each of said plates cooperating with the pair of bolts arranged at one end of the frame, and nuts 5 arranged on the ends of said bolts.

A plate 14 is arranged beneath the mud sill (see Figure 3) and this plate is provided with a slot 15 at each end, adapted to re- In testimony whereof, I affix my signature.
